RAILWAY SIGNAL-TORPEDO. I

Specification of Letters Eatent.

Application filed October 18, 1918. Serial No. 258,716.

To all whom it may concern:

Be it known that I, FRANK DUTOHER, a citizen of the United States, residing at Versailles, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Railway Signal-Torpedoes, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in railway signal torpedoes, and it pertains to that type of torpedo which has become known in the trade as paper or fiber. or non-flying.

The object of my present invention is to provide an improved form of case combined with a novel way of connecting a rail-engaging member thereto.

In the accompanying drawing- Figure 1 is an inverted plan view of a torpedo embodying my invention.

Fig. 2 is a vertical sectional view of Fig. 1, taken in the direction transverse the railengaging member.

Fig. 3 is a vertical sectional view taken through the case longitudinal the rail-engaging member.

Fig. 4 is a detached perspective of the ring or side wall of the case, with the railengaging strap shown in dotted lines.

The case of this improved torpedo comprises a ring 1, which forms the side wall of the explosive containing case. a disk 2 which forms the top of the case, and a disk 3 which forms the bottom of the said case. The explosive compound c'is placed between these disks and is preferably of the tablet form.

As shown, the ring of said wall 1 of the case projects below the bottom 3.

The ring 1, 's provided with oppositely arranged openings 5, through which a railengaging member 6 passes. These openings 5 are preferably closed all around, though they may be made in the form of notches and still embody the generic improvement.

The disks 2 and 3 may be secured within the ring in any suitable manner, but as here shown, the ring is provided with narrow peripheral burs or flanges 7- at opposite edges, with a ring of water-proof cement 8, at the periphery of the top disk 2.

A water-proof cement 9 substantially fills the depression or space formed by the extension of the ring or side-wall 1, below the bottom 3. This cement 9 serves to hold more firmly the bottom 3 in place and to make a water-tight joint between the periphery of the disk 3 and the ring 1. The cement 9 also serves to cement the strap 6 to the bottom 3 and prevent the strap from having an endwise movement.

While I have here shown a circular form of case, I desire it to be understood other shaped cases may be used, such as an angular one without affecting the scope of the invention.

Having thus described my invention what I claim and desire to secure by Letters Patent is:

1. An improved railway signal torpedo, comprising an explosive containing case having a side-wall extending below the -bot-' tom of the case, the extended side wall having oppositely arranged openings, a railengaging member passing through the openings and parallel to the bottom, and a cement uniting the strap to the said bottom.

2. An improved railway signal torpedo comprlsing an explosive containing case having its side wall extending below the bottom of the case, the extended wall having oppositely arranged openings, said openings Patented Mar. 4., 1919.

having a bottom wall, and a rail-engaging member passing through the said openings and below the bottom.

3. improved railway signal torpedo comprlsing a case, composed of a ring, disks within the ring, one forming the top and the other the bottom of the case, the ring pro ecting below the said bottom, the ring having oppositely arranged openings with the lower walls, and a rail-engaging member passing through the openings and parallel to the bottom.

4. An improved railway signal torpedo comprising a-case, composed of aring and two disks within the ring, one disk forming and the extension of the ring for holding the top and the other the bottom of the case, the ring and the strap in position. 10 the ring projecting below the said bottom, In testimony whereof I hereunto aflix my the projecting portion of the ring having signaturein the presence of tWo Witnesses.
